Description
Technical field
The utility model relates to the dynamo-electric releasing device of a kind of cable transmission perforation, for Oil/gas Well cable transmission perforation, the sub-clustering perforation of conventional gas and oil and unconventionaloil pool development field can being applied in, when construction operation without the need to artificially arranging the weakness of cable, strengthening the resistance to tension of cable of going into the well.
Background technology
Deep layer is drive in conventional gas and oil exploitation boldly, unconventionaloil pool enters large-scale development, both the pressure rating ensureing wellhead sealing had been needed in cable transmission process, also need to ensure to go into the well the tensile strength of cable, and domestic cable transmission perforation realizes the present situation that instrument string departs from: 1. must arrange weakness to cable before operation, reduce the work capacity of cable own; 2. meet card in horizontal well operation, weakness effect is not obvious; 3. meet card in catch-basin, weakness effect is not obvious.
Publication number is CN2856382, publication date is a kind of Novel releasing gadget that the Chinese patent literature on January 10th, 2007 discloses that a kind of oil field well construction pipe string discharges locking, and this releasing device is made up of relieving mechanism, retaining mechanism (namely separating sealing mechanism), anchor mechanism, setting mechanism.The mechanism that this device is locked due to employing retaining mechanism and waterpower anchor fluke simultaneously has larger coupling mechanism force, ensure that the synchronism of deblocking simultaneously; In anchor fluke, adopt waterpower anchor fluke Structure anchor first, overcome slips easily broken de-, flimsy shortcoming, achieves bidirectional locking; Can be stressed separately owing to have employed split-type lock ring in solution sealing mechanism, guarantee that each lobe can untie separately the success rate that improve deblocking.This device can be widely used in oil field well construction pipe string release locking operation.
But with the prior art that above-mentioned patent document is representative, still there is following shortcoming in it: the tensile strength of cable is inadequate, cannot be provided as the releasing device that follow-up fishing provides enough large intensity.
Utility model content
The utility model is intended to for the defect existing for above-mentioned prior art and deficiency, provides a kind of cable transmission perforation dynamo-electric releasing device, adopts the utility model, and one is when solving releasing device work in wellbore fluid access to plant; Two is solve releasing device to depart from; Three is solve follow-up salvaging timer tensile strength; Four is without the need to arranging cable weakness, enhances cable tensile strength.
The utility model realizes by adopting following technical proposals:
The dynamo-electric releasing device of a kind of cable transmission perforation, it is characterized in that: comprise electric cap, detonating fuse, blast perforate bypass, blast weakness, sealed guide post, to escape bullet pawl, to escape sealing shroud, to give up jacket casing, piston, relay cover and two female joint, in described sealed guide post press-in piston, involve two ends wire, blast perforate bypass plays pawl one end and is connected with escaping, and the bullet pawl other end of escaping is connected with sealing shroud of escaping, described sleeve press-in of giving up is escaped and is played in pawl, described piston press-in is given up in sleeve, and involve wire, described relay cover is inserted in gives up in jacket casing, described pair of female joint is screwed in relay cover, described detonating fuse is connected with electric cap, blast weakness is fit into blast perforate bypass and embeds in detonating fuse.
Between sealed guide post and piston, perforate bypass of exploding and escape play between pawl, escape play pawl and escape between sealing shroud, give up sleeve and escape play between pawl, piston and give up between sleeve, relay overlap and give up between jacket casing, two female joint and relay overlap between and explode between weakness and blast perforate bypass and be all equipped with O RunddichtringO.
Described blast weakness is that human factor is to a part design one place circumference stress concentrated position, detonating fuse detonation energy is utilized to be carried out blowing up or destroying by stress concentrated position, make UNICOM inside and outside releasing device, form the passage that place's liquid can flow, well liquid is by passage access to plant.
Compared with prior art, the beneficial effects of the utility model show:
The utility model adopts the explosion energy of detonating fuse to blow device weakness, impel in well liquid access to plant, well liquid pushed at high pressure piston moves down, bullet pawl reclaims, give up under the effect of pipe string self gravitation or external cable pulling force, enhance the resistance to tension of cable, also for follow-up fishing provides the device body of enough large intensity.
Accompanying drawing explanation
Below in conjunction with specification drawings and specific embodiments, the utility model is described in further detail, wherein:
Fig. 1 is the structure chart of the dynamo-electric releasing device of cable transmission perforation.
Mark in figure:
1: electric cap; 2: detonating fuse; 3: blast perforate bypass; 4: blast weakness; 5: sealed guide post; 6: bullet pawl of escaping; 7: sealing shroud of escaping; 8: sleeve of giving up; 9: piston; 10: relay cover; 11: two female joint; 12:O RunddichtringO.
Detailed description of the invention
